DG4V36AMWB40

The DG4V36AMWB40 valve belongs to the DG4 Directional Valves series and is manufactured by Vickers. It directs oil flow in automated hydraulic systems by shifting a wet armature solenoid that minimizes friction and internal leakage. The solenoid winding is built to Class H insulation limits so the coil tolerates elevated temperatures generated during rigorous service, while Class F encapsulation surrounds the coil to improve dielectric strength and resist thermal aging. The unit operates on a continuous duty cycle rated at 100 percent ED, allowing the solenoid to remain energized without mandatory cooling intervals. Electrical entry is via a 1/2 in NPT conduit connection, which supports standard industrial fittings and strain reliefs, and with an ISO 4400 plug installed the enclosure reaches IP67 so temporary submersion or high-pressure washdown will not breach internal cavities.

The hydraulic stage withstands 350 bar (5075 psi) on the P, A, and B ports, enabling use in high-pressure circuits common in machine tools and presses. A spring offset end-to-end spool arrangement returns the valve to its de-energized position when power is removed, simplifying fail-safe design. The spool lands follow the pattern labeled P blocked with A and B connected to T, providing a predictable path that unloads work lines to tank while isolating the pressure supply. For mounting, the body matches the ISO 4401-03 interface so it aligns with CETOP 3 subplates without adapters, and the footprint also corresponds to the NFPA D03 pattern to ensure interchangeability with North American manifolds. These mechanical and fluid characteristics position the DG4V36AMWB40 as a compact control element that installs quickly and maintains pressure integrity in automated hydraulic assemblies.
